What is the character limit per slide on a LinkedIn carousel?
LinkedIn doesn't enforce a character limit per carousel slide — since slides are images inside a PDF, not a text field, there's no platform-level cap. The practical limit is legibility: keep each slide to roughly 20-40 words (about 150-200 characters) so text stays readable at the small thumbnail size carousels render at before a reader taps to expand.
It helps to separate this from LinkedIn's actual character limits, like the 3,000-character caption cap — those apply to text LinkedIn's system parses and stores. A carousel slide is just pixels in a flattened image, so LinkedIn has no way to cap its text even if it wanted to; you could technically fit a full paragraph on one slide and it would upload fine.
The reason that's still a bad idea is legibility, not policy. Carousels render small in the feed before someone taps to view them full-size, and mobile screens are unforgiving of dense text at that scale. A slide with one clear headline and a short supporting line reads instantly; a slide with 80 words of body copy asks the reader to stop swiping and actually study it, which most won't do mid-scroll.
A related mistake is shrinking font size to cram more words onto a slide instead of cutting the copy — this defeats the point of the length guideline entirely, since a slide can technically stay under the word count while still being unreadable at feed-preview size if the type is too small. Keeping a consistent type hierarchy across every slide (one headline size, one supporting-text size) matters as much as the word count itself, since it's what lets a reader's eye know where to look first on each new frame without pausing to figure it out.
A reasonable working limit is 20-40 words per slide, split between a short headline (the point) and a line or two of support (the context). Slides that need more than that usually mean the idea should be split across two slides instead of compressed onto one. CarouseLabs generates slide copy within readable length automatically as part of each template, so text density stays consistent without needing to manually trim each slide.
Key Points
- There's no LinkedIn-enforced character cap on carousel slides — they're images, not text fields
- The real constraint is legibility at small feed-preview size, not a platform rule
- 20-40 words per slide (roughly 150-200 characters) is a reliable readability guideline
- If a slide needs more text than that, split the idea across two slides instead of cramming
Example
A recruiter drafting a "5 red flags in a job posting" carousel initially writes a full explanatory paragraph on each slide, then edits every slide down to a 4-6 word headline plus one short supporting line — the deck reads in seconds instead of requiring readers to stop and study each frame.
Related Questions
Can a carousel slide have more text than a caption?
Technically yes, since slides aren't subject to LinkedIn's caption character limit at all — but readability, not a rule, is what keeps slide text short in practice.
Does font size affect how much text fits on a carousel slide?
Yes — larger, more legible fonts (recommended for mobile readability) naturally force shorter text, which is part of why well-designed carousels tend to stay concise per slide.
